INVERTED-LAMP BURNER.

Specification of Letters Patent.

Patented Get. 10. 1911.

Application filed January 7, 1911. Serial No. 601,249.

To all whom it may concern:

Be it known that I, EDWARD H. PALMER, a citizen of the United States, residing at Detroit, county of \Vayne, State of Michigan, have invented a certain new and useful Improvement in Inverted-Lamp Burners, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to inverted lamp burners.

It has for its object an improved constantly burning light, using gasolene fuel or a fuel which must be vaporized by heat and mixed with air before it is burned.

The object of the invention is to so arrange the vaporizer and the air mixer that the action will be carried on when the fire is turned very low.

A-serious trouble in constantly burning lamps using gasolene for illuminating purposes is that the loW fire which is used during the intervals between the use of the device for lighting purposes does not produce heat enough to vaporize the liquid at the place where it is usually vaporized and mixed with air, and the object of this invention is to so arrange the vaporizer with respect to the fire that a very low fire will produce sufficient heat to vaporize the small amount of fuel the constant fire requires.

In the drawings :-Figure 1, is an elevation indicating the general outline of the structure. Fig. 2, is a vertical cross section showing the location of the several parts. Fig. 3, is a plan view of the generator. Fig. 4:, is an inverted plan view of the burner.

The mantle holder and burner 1 is arranged at the bottom of a drop pipe 2 which is coupled to a conveyer pipe (not shown). A hand valve 4 controls the admission of fluid to the drop pipe, the lower part of which above burner extension 6 is the generator. A manually actuated valve 5 is interposed just above the burner extension 6 and is provided with a discharge opening controlled by needle valve 7 which is located in close proximity to the end of the pipe 2 and directly above and in close connection with the extension 6. A short curved conduit 8 spaced from the point of the needle 7 receives vapor generated in the chamber of when the same is actuated by the hand actuated lever 12, and a lug 13 depending from the tube 10' engages with a stop screw 14 which may be adjusted to properly regulate the flow of vapor past the needle valve 7 to maintain the constant fire at its desired minimum intensity. The generator is directly above the burner and would be exposed to heated currents of air rising from the burner through the openings between the arms 16 of the ring which holds the glass bell 17 but direct contact of the currents of air with the generator is prevented by the interposition of a guard 18 which underlies the generator and rises at each side thereof, furnishing a guard for the inflow of pure air necessary to produce a proper combustible mixture and also preventing the accidental dropping of vapor and consequent ignition of vapor at the discharge orifice around the valve 7. A second guard 19 passing across the nozzle around valve 7 and extending at each side of the mixer parallel therewith and spaced therefrom slightly, prevents eddy currents from catching and driving away from the mouth of the mixer the vapor which is passing across the gap of the air break. This second guard is especially useful because of the comparatively low pressure of escaping vapor and at the same time comparatively low velocity of rising heated air during the period when the fire at the burner is maintained very low.

What I claim is 1. A vapor-burning lamp, having in combination a drop pipe, a valvecontrolled nozzle therein, a conduit pipe forming a mixing chamber having an opening spaced from the nozzle and registering with the opening in said nozzle, a burner at the end of the conduit pipe, a guard above said burner adapted to deflect the heated gases therefrom to either side of said nozzle and opening in the conduit pipe, and a second guard above said first-mentioned guard and closely inclosing said nozzle opening and conduit pipe opening, thereby adapted to protect the vapor passing through the space between the two openings when the pressure is low, substantially as described.

2. A vapor burning lamp, having in 00111- bination a drop pipe, a valve-controlled nozzle, opening at the side thereof, an extension pipe in axial alinement with the drop pipe, a curved conduit pipe having an opening spaced fron1,t-he nozzle and registering with the opening in the nozzle, the said conduit pipe curving out and returning to the extension pipe into which it discharges, a burner on the end of the extension pipe, a guard disposed between the outer run and the return run of the curved conduit, and a second guard disposed about the nozzle and opening of the conduit pipe, whereby the vapor passing through the space between the nozzle and the conduit opening is protected, substantially as described.

3. A vapor burning lamp, having in combination a drop pipe, a valve casing terniinating said drop pipe and having a nozzle opening at the side thereof, a needle valve engaging in said valve casing, a lever adapted to control said valve, a conduit pipe having an opening spaced from the opening of said nozzle and registering therewith, the said conduit pipe extending outward horizontally and curved back to an extension from said drop pipe, the said extension from said drop pipe connected with said conduit pipe, a burner in the end of said extension, a guard disposed between said burner and 5 the nozzle and a second guard Within the first guard disposed about the openings of said nozzle and conduit pipe, substantially as described.

In testimony whereof, I sign this specifi- 4 cation in the presence of two witnesses.
